You knock on Leviathan’s door, three times, a short pause, and then two more so he would know it was you. Typically, it was only a few seconds before he demanded the password from you, but after a long moment, it’s still silent. You raise your arm to knock again, before you hear him huff, “What?”

You frown. “Levi, it’s me.” 

“Arrruggghh!” He sounds frustrated. “Go away!” 

Now, you’re getting a little angry. “No.” You retort. “You haven’t come out of your room in almost two days.” While that wasn’t terribly out of the ordinary, this time felt different. Usually when locked away in his room, Levi would at least message you. If not to tell you about whatever game he was playing, or anime he was binging, he’d ask you to bring him something to drink or eat. Or to wait outside while it’s delivered and then bring it to his room. 

Annoying, yes, but Leviathan had become… special to you. He was endearing. Levi didn’t have ulterior motives like some of his brothers, or motives that you at least weren’t sure of. What is Lucifer ever even thinking? Or Belphie? Or Satan?! But with Levi there was no questioning. He was earnest in that way. And while some might say his otaku hobbies were annoying, you enjoyed a well-done shounen and the occasional MMORPG. 

If this were a different brother, you’d probably leave them to stay in their room, but you were concerned for Levi. He’d let himself get sick before locking himself in there: a ruler of hell could be brought down by only himself. You were worried. You’d brought him spicy pizza, and a soda you could only get in Japan that he’d ordered and hidden in the kitchen. 

You wait at the door, contemplate knocking again to let him know you were getting impatient. 

“I said go away!” 

“And I said no!” 

“Aaaauughh, you don’t get it MC!” 

You never do, in spite of the harrowing tasks you’ve completed for Levi on your quest to prove that you’re really not a normie. 

“Levi, I’m coming in.” 

“Don’t!” 

Your hand is on the knob, and you turn it. 

Levi panicked, as he often did, but this time it was really, really, really bad. Unlike his brothers who would occasionally skip their heat suppressants to go out on the town, and find someone to fuck or kill, but usually both, Levi never did. Why would he?! 

Imagine it!! Him… trying to find someone to ride out a heat with. It’d happened before, but it was just because of his brothers. He was positive they did it to play a trick on him. (“What would we even gain from that?” Lucifer had asked.) So once the option became available, Levi was religious with taking his suppressants. It just made things easier! He could enjoy a hentai every now and then but not this….hot, sticky, need that thrummed through his bones, this pounding in his head and joints that told him to hold anything down and fuck it til it stopped moving.

The last time he was supposed to take his suppressant just so happened to be the Sucre Frenzy mini album pre-release. There was a live chat he had to be there for, a raffle to win tickets to their meet and greet, and then as soon as the album dropped, he had to buy it digitally AND wait for his physical copy to get there so he could see his photocards and the photobook. Then of course, that package got stuck at the Akuzon center and he had to go get it. As in: leave the house of lamentation, and go to Akuzon, approach a stranger, and then initiate a conversation. 

Turns out the package had just been too heavy - he had to make sure he got all the photocards so he’d ordered twenty - and he had to sign but the whole ordeal exhausted him! He went back to his room, and listened to the physical album, put away his photocards, stored everything properly, posted reviews, and of course commented on every Devilgram post about it. It was an event and the next few days, of course they were going to be promoting. He had to be by the computer to watch every performance, every fancam, every MR removed video, leave thoughtful commentary, and report the hate comments. 

And by the time he’d realized what had happened, it was five days later. And he hadn’t taken his suppressant. And he couldn’t now?!! He’d have to talk to someone, and explain what had happened, and having to talk to someone was bad enough but then he’d have to say why he missed his last dose, and that was… just not going to happen. 

He could ride this heat out. He had lotion, an extensive collection of video games, movies, and manga, and several dakimakura he could use to help. Not that he needed any of it; he’d been hard since yesterday at breakfast when he’d seen you. You had to come down in your pajamas, no bra and shorts that were big so they rode down your hips. He thought he was going to lose it, but he yelled an excuse, stood up quickly and headed straight back to his room. 

“I wonder what’s wrong with him?” He’d heard you say as he left. OF COURSE you wouldn’t get it!! 

Why did it have to be you who came to the Devildom? Why you? There had never been a human before that did this to him. He’d met humans with his interest, fellow otakus who didn’t understand the eons of love and devotion he’d put into his fandoms. He was a fan before there was even anime!!! But that didn’t bother him when you had said, “well, yeah hasn’t everyone watched at least one anime? Like pocketto-mon?” 

No, MC, they hadn’t!! 

But you had! And you had to come to stay in the house of lamentation, and liked The Truth in September and the Attacking Giants, and had even shown him ones he’d skipped over when they first came out, like West of Eden, and Katekyo Mafia Rebirth. And you’d come into his room to watch them without any makeup and your hair tied up so he could see the lines of your face, nothing to obscure your smile and laugh or even tears at sad parts. 

And you always smelled nice! And you never told him he was gross! Your skin always looked soft, and you didn’t laugh at his laugh, and you knew the dance moves to the Kosomatsu-chan openings, and your stupid body looked like a manga he’d read once about a girl who liked tentacles a little too much, and it made him want to both never think about it again but also think about it all the time. 

And now… now you’re on the other end of his door. 

And his dick is out. Hard, and twitching in against his stomach. Staring back at him. 

He’d already cum til his hand was raw, and he’d used two body pillows to the point that he felt dirty even looking at them now. It was nowhere near over. It had been building up for… years at this point, longer than you were alive, and now you were here on the other end of his door. It was you. It was your knock. 

So, Leviathan panicked, and said, “Go away!” 

“No,” 

You weren’t going anywhere. He couldn’t make any sounds, so he bit his lip and shoved his dick back into his sweatpants. It didn’t hide anything. His face was probably crimson, and you could see it straining against the fabric. He grimaced. Couldn’t he just die instead? This wasn’t gonna work. What would he even say?! 

“I said go away!” He spits out. He knows it’s not going to work.  

“And I said no!” 

“Aaaauughh,” He puts his head in his hands and yells, “you don’t get it MC!” 

He hears you huff an exhale. You’re annoyed. He wanted that. Maybe you’d be mad and leave. That was his only hope. He’d apologize later, you just could not be in the room. It would all be ok if you weren’t in the room. 

“Levi, I’m coming in.” 

FuckfuckfuckfuckfuckfuckFUCKINGFUCKFUCKFUCK--- 

“Don’t!” He stands up, in his demon form but in his sweats, shirtless with his hoodie unzipped. It was too hot, the room had to smell, and even if you were a human, you’d know something was wrong. He had to keep trying to piss you off bad enough to leave. 

When the door opens, he’s right on top of you closing it. He’d hoped to shut it before you came in, but his speed was nerfed by his dick. 

So, arguably the worst thing had happened. You were back against the door, the pizza and soft drink on the floor, with his body hovering over yours. 

“Kabedon?” You laugh, unaware, trying to take his mind off the situation. 

He was going to explode. Or spontaneously combust. He just had to. He’d rather do either of those than explain what was going on. 

You realize the joke had fallen flat, when you see his teeth gritted and fangs out. “Levi, what’s wrong? You haven’t been like this since-”

“Shut up.” He grunts out. “What are you doing here? I said leave!” Yeah, that sounded angry. He just had to get you out of his room. He’d fix it all later, you just had to leave. “What do you want?” 

You blush, and choke up a little, taken aback by his tone. He’d been mad before, but endings-that-weren’t-like-the-manga-mad. This was different. Very different. He had an energy beneath his words, powerful and boiling underneath. “I-I-I hadn’t seen you since breakfast yesterday, and was worried. I brought you-” 

He drops his head to your shoulder, his face feels so hot. Is he growling? Like really quietly? You gulp, and whatever you swallow drops from your stomach lower. Why’s it kind of...hot? You bring an arm up over him to pull him a little closer. “Are you ok?”

You weren’t worried - you were trying to kill him. He was certain. His nails were digging into the wood of the door behind you. “N-no, you need to leave.” 

“What’s wrong?”

Fuck, he was going to die. He was going to just pass out here, and wither away and honestly it seemed ok at this point. “Ah-” He chokes out, and you feel the realization wash over you. “Demons go through- through heats.” 

Your eyes widen and you inhale. It smells different, musky like a humid woods and malty like a beer. You breathe in deeper. “I’ve---I’ve read about that.” 

Levi swallows and brings his head up to look at you. “You need to leave now.” You dart your eyes to the ground, but he holds the stare. He’s blushed before but his face is a faint red but his orange eyes are glowing. He’s breathing through his nose, and he looks both tense and drunk somehow. 

You didn’t want to leave though. “Do you-- can-can I help you?” You bring your eyes to meet his. 

He clenches his jaw, “No-- this isn’t like when I normally get sick.” If you stayed any longer, he wouldn’t be able to control himself and he’d probably cum all over you just standing there underneath him.  He’s shaking and his dick is painfully hard. “You need to leave.” 

“I don’t want to.” You're firm in your answer, the gears starting to turn in your mind. “Let me help you, Levi.” You close the space between the two of you and kiss him.

He doesn’t protest again. Normally his brain would be screaming at him to push you away, and to run away. But his brain isn’t what’s thinking. He’s too far gone to feel embarrassed or unsure, and your lips on his did nothing but push him further. He crashes his lips onto yours, what he lacks in grace, he makes up for his passion. His hands go to your waist to wrap you tightly to him. You can feel his arousal, hot, hard, and.... It doesn’t feel like any human you’d been with before. It’s thicker, and the outline feels different. You push back against him, wanting to feel more. 

His forked tongue pokes at your pursed lips, and you oblige, letting the thin appendage lick inside every inch of your mouth. You bring your arm down from around his neck to trail a hand across the scales along his neck, and moan into his mouth. He shudders against you. It had been so long since he’d had any contact like this, and your soft warm body pressed against his felt so inviting. You’re kissing him back and instead of trying to pull away, like he’d always assumed you would, you’re pulling him closer. You’re making little sounds that make him want to kiss you forever, and you smell so good. He’s going crazy. 

Much to his own dismay, he felt the pressure in his belly. He was going to cum, again, without you even touching him. Just the sounds and pressure from your clothed body against him. Normally, he’d be so embarrassed he’d want to die, but your body underneath him feels so good, he can’t care. “MC--” He pants into your shoulder, “I’m gonna-gaah--” He pulls you impossibly closer, so you can’t look at or escape him, and his hips spasm against you. Even through your clothes and his sweatpants, you feel a hot wetness against both your stomachs. Your eyes widen, and you feel...a little disappointed. You’d really wanted to do more - like a lot more - but you see the member that was poking into you, and probably staining your shirt. 

Wait, if he was coming...why wasn’t he.... Getting softer? 

He’s stopped by now, but his grip on you hasn’t loosened. In fact, he brings his tail behind you to pull you even closer, his head still buried in your shoulder. 

“Levi?” You ask and he mutters something into your hair. “Are you--”

“It’s not over,” He grunts, his voice gravelly and unsure. 

You start to question, but he cuts you off. 

“It’s been like this since last morning, and I don’t know how long it’s gonna last.” He says, not looking up at you. “It’s humiliating.” Even though you can’t see it, you can feel his blush against your skin.  

“Why?”  

He picks his head up to look at you, eyes wide with surprise. “You don’t…” He starts, still holding you tight to him. “You don’t think it’s… gross?” 

You shake your head vigorously. “No,” In fact, it was quite the opposite. “You can...keep going?” Your eyes go to look between your bodies, where you know his erection was still pressed up against you, hard but hidden. Because of your positions, you were sure he couldn’t feel it, but your own arousal was becoming very apparent to you. If this could continue… 

He blinks, his pupils slanted and serpentine, and his mouth twisted. He wanted to say something, but it was caught in his throat, and all he could get out was, “ww-with me?!” 

“Yeah, I wanna-” 

“Wait-” Levi steps back, both the wet stains on and the tent within his pants very visible. He’s eyes are shifting, but still reptilian, and his hands are shaking. “Before-before you say that, I wanna tell you.” 

This was it. “Yeah?” You nod, eyes wide, ready for a top-tier anime confession. He was gonna confess that he liked you from the moment you stepped into the devildom. The bridge scene in Tiger-Dragon has nothing on what’s about to go down, you think. “What do you wanna say?” 

“My dick looks weird.” 

You blink, twice. “I’m sorry?” 

“It looks weird, ok?! You don’t have to if it freaks you out or any-anything!” He starts to stammer. 

“When you say weird…” 

“It’s not like in hentai.” He frowns, and looks away, his eyes focused on the ground beside him. 

Oh, sweet boy. “Well, yeah, I’m sure it’s not.” You move to approach him, to soothe his ego. “Nothing’s like in hentai, it’s unrealistic!” 

“Not like that!!” He’s even more flustered. 

“Ok, Levi, then what?” 

“Urrggh! Just lemme show you!” In a moment of unprecedented boldness, Levi yanks down his sweatpants.

He was right. It wasn’t like hentai. Well, kind of. 

Levi’s dick was a tentacle -- actually what looked like two longer tentacles, and maybe four or five smaller ones around the base, all a blueish purple hue. Each had one row of suction cups wrapping around it, varying in size depending on the girth. The two larger ones are relatively still, pulsing with what you imagine is his rapid heartbeat, but the smaller ones are writhing around, very clearly still not done. Slick from cumming earlier, you can see them glimmer ever so faintly in the dim aqua lights of his room. 

Your jaw has to be hanging open.  

“Augh,” He yells, and reaches down for his pants. “I knew you-”

“No, no, no!” You clear the space between you, holding out your arms and shaking your head. 

“Huh? You’re not--” His blush is back, brighter than ever, creeping up to his pointed ears. “You’re not disgusted?” 

“Can I… can I touch it?” You reach out towards him. 

Levi is so shocked his eyes must cross for a moment. “You want to?!?” 

You nod your head. In spite of Levi not being willing to admit it, you weren’t exactly a normie when it came to what got you off. Before you had to pay for fakku, “tentacles” was a frequent tag for you. And this… a dream come true? A tentacle monster that could do all the vile things you’d read, latch onto your tits, the inside of your mouth, the inside of your… And it was attached to Levi? Levi who would be blushing like this the whole time, and sticking his snake tongue down your throat, and held you so tight when he came, you think he’d left bruises. “Yeah, I want to touch you.” 

He says nothing, but you see him bite the inside of his cheek. You tentatively reach your hand forward, ever so slightly touching the tip of one. 

“Aaaah!” He cries out, almost in pain. 

“I’m sorry!” You pull your hand back. “I’m sorry, I’m sorry. Was it too much?” 

“No!” Levi says, his voice almost breaking. “No! I just-” He looks away, clearly ashamed to tell you, but deciding he was already this far in. It had been years since anyone besides his brothers even saw him like this, let alone touched him, but then it was YOU with your soft pretty hand touching him. “I haven’t been with someone in… a long time.” 

You smile. God, he’s an idiot, and for some stupid reason, it made you wanna fuck his tentacle dicks in his stupid bathtub bed, with all his figures watching, and the lulling of the idle desktop as your BGM. “We don’t have to do anything you’re not comfortable with.” You reassure him. “It’s been a little while for me too.” 

“You don’t have to lie...” He pouts. 

“I’m not lying, Leviathan.” Why again do you wanna fuck him in the bathtub? Why do you want to fuck the demon with his cum stained sweats around his ankles in his bedroom full of anime posters. What more do you have to do to convince him? “I wanna do… whatever you wanna do. And whatever you need to do.” 

“It’ll take a while.” He still hasn’t made eye contact with you again. This is so absurd. His dick is out, but he won’t even look at you. 

“Ok,” 

“And I don’t know how long it’ll be…” He goes on. 

“Uh huh, that’s ok.” 

“And I don’t know what human girls really like…” 

“That’s ok. I’ll tell you what I like.” You like tentacles. You like him. You like his stupid blush, and his little fangs poking out of his mouth, and his spikey horns, and his weird personality, and how he sings the opening to Demongelian every single time you go to karaoke. And you’d tell him all this if he gave you a chance. 

“And, once I do it,” He’s barely moving his lips at his point, mumbling like he has a mouthful of food. “Uhrguhnnahbmihne.” 

“What?” 

He says it again, but somehow both faster and quieter. 

“Levi, I can’t hear you.” Again, your mind is screaming: why...why do you want to fuck him? Is this huge tentacle dick rearranging your organs fantasy worth all this? 

“I said, once I do it you’re gonna be mine!” He yells. “I’ll get too jealous if you’re with anyone else and it’ll be like the TSL competition all over again, but even worse, ok?! So, after this, you’re gonna be mine and no one else can have you! Or even think about having you! Ok?!” 

Levi was always worth it. “Ok,” You agree. It doesn’t take any convincing. When the time is right, you’ll tell him the decision was easy for you, and you’d had wanted to be his all along. “I’ll be yours after this.” 

He chokes on an inhale. The demon is commander of Hell’s royal navy, and the third most powerful of all the demons in the devildom, and he can’t breathe when he’s about to have sex. “Really?” 

Oh for fuck’s sake. “Yes, I’ll be all yours after this, Leviathan. I’ll be your Henry forever. What do I have to do to prove it?” 

“Well,” His eyes move from the side of the floor he’d been staring at to your feet. “I’m-- I’m kind of naked, and you still have all your clothes on.” 

He was right. Without thinking much of it, you pull your shirt up over your head and toss it to the floor. You start to make work on your pants, and his eyes shift up. He doesn’t say stop, even though there’s still a part of his brain screaming that. He was in heat, but he still was who he was. He thought about this before - you taking off your clothes in front of him - but he’d always imagined it would be all he’d get to see. He never thought you’d be taking off your clothes after offering to touch his weird monster dick. It was happening too fast, but he didn’t want it to stop either. You--you wanted him too right? So, he could look at all of you, right? 

Oh shit, you were there, in your cute bra and undies in front of him. And they were both black, and they matched, and had little lace around the edges, just below your belly button, and around the curve of your breasts. He wanted to look forever, remember you in the dim light of his room, undressing after he’d just kissed you and came all over your stomach--oh fuck. He was so hard, he felt it in his teeth. 

“Can-” He finds his voice, as your hands move to your back to undo your bra clasp. You freeze, and he does too before he finishes. “Can I--can I touch you too?” 

“Yeah,” You barely whisper. “I’d really like that.” You say so he can hear you. 

Finally, his hands and arms are back on you again, this time with no clothes in between. His skin is hot, damp, and slightly scaly. You let out a breathy moan when he presses his hand into the small of your back, pushing you into him. His top dick is twitching against your stomach, and the lower one is being pushed against your panties. You feel the cool of the suction cups, and the heat of the flesh underneath. 

“Fuck-Levi,” You wrap a hand cautiously around the top tentacle, and start to move your hand. They don’t stick to you like you thought they would, but they’re just as slick as you thought, making the movement easier. “Is this ok?” 

“Yeah,” He huffs. “Yeah, it’s good.” His hands are shaking. You said he could touch you but he didn’t know where to start. It’d been years, but your hand on his upper member shot a message straight to his brain, and before he could think his hands found your breasts. You let out a small wine, the pressure enjoyable but not enough. Your breasts are soft, and firm against his hands. He felt his brain short-circuiting, small explosions lighting up behind his eyes, when he brought his mouth to yours again. 

This kiss was bolder - he had your permission, and your hand speeding up over his one member made him want to run his tongue meticulously over every tooth and crevice in your mouth, see how far down your throat he could go. His lower member was writhing against a wet spot in your panties. Oh god, was it wet from him? Or wet from...you? He moans at the thought and you eagerly swallow it, grinding onto his other member while continuing the movements of your hand. 

You can feel both pulsating against your hand and your core respectively. As enjoyable as this was, your mind drifted to how they’d feel inside. Would they stop moving like that, or would they move faster? Would they suction onto you? Where does he even cum from? Before you take things to that step, you wanted to see him cum again, and actually see it this time, not have him hide from you. 

And again, much to his chagrin, he was close, again. God, why was it just your hand that felt this good? It was softer and smaller compared to his, and the force behind it was almost delicate, like you still wanted to be careful with him. Even just the pressure on his lower member was sending sparks up his spine. Naturally, he’d thought about this when he was humping his body pillows, his hands on their fake tits, and his face hiding in the fabric. But this was beyond that. Your warmth, and how you responded, never saying his snake tongue was gross but letting it lick around your mouth. He separates his mouth from yours, grimacing knowing he was so close already. He moves to hide his face in your shoulder again, but you lean back. 

“No, I wanna see your face.” You tell him, and the sentence alone makes him cum before he can even think to hide. His moan is initially surprised, by your boldness and by his own embarrassing speed, but faded into a low groan as he covered your hand in his cum, spraying from his tip. You watch him against your hand, wishing you could see both members at the same time. He rides it out, continuing to buck against your hand, and keeping his eyes screwed shut. You wanted to see, but he didn’t want to… It’d be too much. He couldn’t do it, not just yet! 

The sensation for him dies down, still hard but slowing his thrusts until you’re just holding his member in your soaked hand, and between your drenched thighs. It was so much. It wasn’t like human cum, you noticed, bringing your hand closer to inspect it. It was slightly thicker, and maybe it was the light of the room, but it glowed a little? Not sparkly like glitter, but it definitely caught the light as you moved your hand. 

As Levi comes to his senses, he sees you raise your hand to your mouth and take a small lick of his own cum off your hand. He cries out, “are you trying to kill me, MC?” 

It tasted like ocean water, no hint of bitterness but definitely salty. You repeat the action, making sure not to break eye contact with Levi, who was clearly embarrassed but wouldn't look away. You’d be there forever if you wanted to lick it all off, so you opt to rub it his on his hoodie (you’re sure he’d forgive you) and kiss him again. He had tasted himself before - he was curious ok!?! - but mixed with your own saliva, he hungrily opened his mouth for more. It was your turn to map out his mouth with your tongue, and he obliged, letting you slide against his tongue and the roof of his mouth until you were both gasping for air. 

“Do you--” You huff out, “wanna lay down?” 

“Yeah,” He nods, and looks to his tub. “Lemme uh-” He didn’t want to outright say, “lemme me my humping pillows somewhere else” but that was what he had to do. He shucks out of his hoodie, and lets it fall to the ground as he steps out of his sweats. You follow him, seeing his scales lining his neck, his torso, his back, gleaming in the dim light of his room. You want to touch them, and taste them too but you know you have to give him a moment to recover. You wanted to take it slower with him at first. He’s still Leviathan, even if he’s going through heat. You just jacked him off, and he still used his tail to cover the dick you literally just had your hand on. 

He rolls up blankets and lines the bottom of his bathtub with them, making sure the characters faces are downwards, and then covering those with a few pillows, before motioning for you to lay down. 

“No, you lay down.” You say. “I wanna ride you,” He’s getting used to how bold you are, not making a sound but blushing as he sits himself down in his tub-bed. In spite of yourself, you feel the flush creep up your cheeks too. 

He’s sitting up, and you position yourself on his lap, the lower tentacle sliding against your clothed but soaked underwear, the upper one resting against your stomach. He inhales sharply at the touch, but tries to maintain eye contact with you. His hands come up to your chest again, but reach back behind to fumble with your bra clasp. He frowns, so you move your own hands back and help him out, his blush reddening more at the idea that you had to help him but the thought leaves his head once the bra is gone. 

Levi loved boobs. Most otakus do. He had been often quoted as saying, “Nothing beats 2-D” but with breasts, that was not the case. His hands went again to squeeze yours and you moaned as he was less gentle than before. He could feel your nipples now, against his sweaty palms, and moves to play with the nub between his fingers. Even hyper-realistic VR couldn’t beat this, especially with your reactions, a soft moan at his first touch, and growing higher in pitch as he moves his fingers more. 

You lean down to kiss him, so you can hide these little sounds you’re making, but Levi’s mouth lands on your neck before you can. You feel his fangs graze over your pulse, as he licks a strip down to your collarbone. His mouth continues to descend until he reaches his target. 

You feel his lips close around one nipple, a forked tongue coming out to lap at the sensitive bud, and you throw your head back. Heat rushes through you to your core, and you grind down on his lower tentacle, feel remnants from his previous completion and your own arousal pooling together. Levi continues his ministrations, switching between your breasts to suck on one nipple, and to rub the other with his thumb. He lets out soft, pleased little “mmphs” and “MC-” 

You can feel his organs writhe against your stomach. His lower extremity slides in a way you didn’t know it could: back towards his own body, only to come back through your soaking panties to rub against your folds, wriggling pleasantly between your lower lips. You buck against him, and his mouth leaves you for a moment. 

It wasn’t entirely him: you were wet . He could feel it dripping from inside you onto him. Oh god, it was hot, and soft, and waiting for him, and he was losing his mind. The second he was inside you, he was sure he’d blow his load, but he didn’t care. “Can--can I?” He huffs. 

You don’t answer but reposition yourself, so he’s at your entrance, taking in just the tip of him. He doesn’t wait for more, and pushes in all the way. He’s longer than you thought, and as he goes deeper, he gets wider. You let out a strangled cry as he fills you. 

“Sorry-” He starts to pull out. 

“No!” You yell, “keep going. Wanna feel it.” 

He places a kiss between your breasts, burying his head between them, as he fully enters you again. It was everything he’d imagined: velvety soft around him, damp and hot, and you clenched yourself just so to feel like you wanted him deeper. When he bottoms out, he stops, trying to not cum immediately. The smaller tentacles around his base continued to wriggle, until it lands on your clit. You inhale sharply as the small appendage brushes against your bundle of nerves. 

“Does that feel--” He starts, sputtering out his words, trying to focus on your pleasure, even just finding out what you like before he cums again. But the pressure on his dick feels amazing. He knows within three thrusts, it’ll be over for him. 

“Yeah-yeah,” You nod your head, seeking the combined fullness and pressure on your clit. 

Still not moving inside you yet, he lets his smaller tentacles brush against your sensitive spot, and lets his mouth go back to your breasts again. He can hold out a little longer if he doesn’t move inside you, in spite of your muscles squeezing him like a vice. He’ll be able to cum again, he knows - god, does he know - but he--he never thought he could make you feel good. Not good like enjoying a show or movie together. Good like huffing out his name, and grinding on his monster dick, and running your hands through his hair. He was in a dream. He had to be. 

You move your hips of your own accord, but Levi growls against your nipple and moves both his hands to your hips. “Don’t move-” He holds you in place, reminding you of his strength. “Wanna make you feel good before I cum again.” 

You cry out at his demand, and the tentacles at your clit speed up, moving rapidly across the bundle of nerves. He continues like this for a while, kissing and sucking his way back and forth across your chest, as his tentacles assault your bundle of nerves. This and the pressure inside you, the way you could feel his heart beating through his dick, just sitting inside you. You whimper, wanting to move more. 

“Keep making sounds,” He brings his mouth up to your neck, and sucks there, holding you impossibly still. 

You cry out as a tentacle stops brushing past your clit, but latches onto it. “Fuck-” It’s building. Just a little more, just a little more. “Fuck-Levi,” You chant his name softly, as the tentacles starts to mimic a sucking sensation. “Gonna-” 

Your release is immediate, like someone unplugged you and plugged you back in, everything lighting up at once. You slump against him, and let the sensation run through your body, going from your core to the tips of your toes.

Keeping his smaller tentacle latched onto you, he pulls his hips back, and thrusts once, enjoying the sound echoing throughout the quiet room, and then twice more before it’s all too much for him: your skin by his mouth, your cunt latching onto him, your breathy moans of his name. He cums, biting down on the skin nearest his mouth to quiet his embarrassing cry. You can see his upper organ sputtering cum out onto both your bare stomachs, and feel the organ inside you pumping you full. 

You come down from your high, and find his mouth with yours. He kisses back, and your mouths effortlessly slot against each other now, back and forth sucking on each other’s tongues. He bits your lip softly. “MC, I-I-” He starts. “It’s not over. I have to keep going.” 

Your head is spinning, and you feel like you’re underwater. He’s still latched onto your clit and in spite of him finishing, the organ kept a firm hold on your bundle of nerves. He could feel it twitching under him. 

“So that--” He starts, “feels good for you?” His tentacle starts to mimic a sucking motion again, and choke out a cry. It’s like every nerve is on fire, everything still so sensitive. 

“Yes, Levi,” You choke out. It’s so much. He’s so much inside you, and all you can feel is him everywhere, on you, inside you. It buzzes through your nerves like an electrical current. 

He’s blushing like crazy but keeps the pace of his smaller tentacle, while pushing the other back inside you, wet, tight and still waiting for him. If his eyes didn’t cross, they rolled back into his head. There’s no way it’s real. He can’t believe it’s real, but you squeeze his member and cry out as he starts to move again. His hand moves from their steady grip on your hips to your back to push you closer to him, giving him access to kiss, and suck, and bite whatever skin is accessible to him. He kisses over blossoming bruises, salty with your sweat and his cum. “You’re mine,” He says into your neck, hot and wet. “You’re mine,” He repeats between nibbles. 

“I’m yours, Levi,” You say in a haze as he drags you through another orgasm, all his tentacles twitching inside and outside of you. You hold onto him as you ride the wave after wave of pleasure he pushes you through. 

Your head feels fuzzy when you come down from your orgasm, but Levi is still attacking your neck and chest, thrusting and twitching in all the same places. He doesn’t let up at all. You see his serpentine eyes focusing on you, pupils the whole length of his eye, and wide. “You look like a hentai scene,” He growls. “You sound like a hentai. Wanna go forever. Wanna make you cum forever.” 

You cry out, the room is spinning and you’re drowning in him. “It’s so good, Levi,” He bites at your lips and you open your mouth for him to kiss. 

“No, keep talking,” His voice is still low, but he’s almost begging. He’s close again, and you are too. “I wanna hear,” 

“Levi-aah,” Your voice breaks as he makes you cum again, and with a few more thrusts, he joins you. 

He rubs the cum across your belly and up your chest, over your hickeys and tits. “Mine, mine, mine,” He repeats, not ever stopping his thrusts, fucking his cum back inside you. 

“It’s--so much,” You stutter. The pressure on your clit and back of your pussy hasn’t let up this whole time. “It feels so good.”  

You feel swollen under his tentacles and start to sob at the sensation. He slows the pace of the tentacle sucking your clit, but never lets off it. He wants to make you cum over and over. The game no one thought he’d ever win, he wants to win over and over. He wants to play the level again and again until you’re begging him to stop. 

You wake up on top of him, with his organ still buried inside you. Your stomach, up to your breasts, and even a little at the longer ends of your hair, have cum splattered on them, drying slowly. A little foggy, you hear Levi say, “I’m sorry, MC...” 

You shake your head a little, to try to wake yourself up more. “Why?” 

He mutters something you don’t hear, and he looks away from you. If you were fully awake, you’d remind him that his dick’s inside you and you really don’t need to be embarrassed telling each other things. But instead you stretch your arms over your head, feeling a little pull in the space where you met and cum had dried. 

“What?” 

“When you were asleep…” He started, and then trailed off. “I uh… I’m sorry I couldn’t stop.” 

You blind a few times, understanding. “Did you fuck me when I was asleep?” 

In spite of being naked and inside you, and you being naked, on top of him, and partially covered in his cum, his face flushes bright and he stammers. “I’m so sorry-- it’s the heat.” He looks frustrated, and truly apologetic. “It just doesn’t stop. Even now, my brain’s telling me to keep going.” 

You bring your hands to cup his face and kiss him. “It’s ok,” You reassure him. The idea was actually sort of hot to you, but you’ll tell him that later. “What do you need me to do for you?” You ask, a little bit of sleep still clouding your voice. 

“Gaaah,” He barks out, and his hands fly to your hips as his own start to move furiously up into you again. “Just stay there,” His head lulls back against the tub. “You don’t have to do anything.” 

You curl your body down onto him, so his neglected cock receives some pressure from you sticky belly, and he moans out, “MC, feels so good. It’s so good.” 

His face is splotchy red, some spots brighter than others, and his bangs are stuck to his forehead from the sweat. He’s breathing through his open mouth, air coming out in huffs and puffs as he feels himself plunge into you again, and again. 

If his pounding wasn’t what woke you up, his smaller tentacles began to move against your clit again. You scream. It’s so sensitive from whatever had happened before that made you cum til you passed out. “Leviii-aaah,” 

“MC,” He breathes over and over until he pulls you down all the way to him, to ride out his orgasm with as much of your skin on him as he can have. 

The movement stops for a moment, giving you some relief on your overstimulated clit. You let your head sink onto his shoulder. He moves his arms to circle around you tightly, and he pushes himself up a little with his feet. After some maneuvering, you’re both sitting up, him still buried inside you with his back pressed against the edge of the tub, and your knees on either side of him.

He brings one hand to the small of your back, massaging it gently, and another hand to your hair. “I know you’re exhausted,” He says, “But I have to keep going. It’s not done yet.” 

You don’t respond, head fuzzy. You coax a, “mhm” out of your throat against the purple scales on his neck. 

“Here, you don’t have to move.” He says, and the hand at the small of your back moves down to cup your behind, squeezing a little before his hips start a slow rocking rhythm back up, in and out of you. “Just stay, stay like this.” He pulls you close again, his upper dick pressed between  your stomachs, and his lower one slowly going in and out of you. The pressure from your position does nothing but push on your overstimulated nerves, and you let out a pathetic cry into his neck. 

You bring your arms up to wrap around his neck, affectionately laying your head on his shoulder. You whimper a little as the pressure against your clit and the sensation of him wrings another orgasm from your overstimulated body. Your nails dig into his shoulders, holding onto him for purchase as you shake.

“I’m so sorry,” He apologizes, as earnestly as he can gruff out while still rolling his hips into yours. “I have to keep going until it’s over. I’m sorry,” 

He’s still embarrassed, embarrassed because of his body that’s made you cum so many times you’re floating, embarrassed because of something you said you wanted to do with him. 

“It’s ok, Levi,” You say, your brain fuzzy and hot. 

He keeps going, not acknowledging that he heard you. 

“It’s ok.” You continue. “I want this, and I’ve wanted it for a while. I love how you make me feel, and I want to be here with you til this is over.” 

He swallows a grunt, and you feel his hips stutter a little before he falls back into his pace. 

“I want to feel it each and every time you cum from now on.” 

“Gaaah-” You felt him spill into you, dribbling out onto the tub, and shooting up from between your two combined bodies. 

“I--” He whines. “I have to keep going.” 

You just nod. 

He sinks his teeth into the soft skin of your neck, and starts the motion of his hips back again. He rocks into you over and over again, until he collapses onto you. He goes on for what feels like hours, and you have no idea how long it’s been. You let him move your body how he needs, holding your hips in place, or moving them up and down on him as necessary. You can’t cum again, you keep thinking, but he pulls another one out of your body, from the deepest depth of you. You’re in and out of it, feeling like you’re underwater, being brought up for air just for a moment before he drags you back into the pleasure. 

He lays you down at some point, caging you between his arms, still connected with you. He’s exhausted. It’s normally not this long for him. He doesn’t have the stamina for this. He knows what it normally takes for him to finish, but he’s not sure if he can ask that of you. Not after all this… 

You’re pliant in his arms as he pulls out. He looks down at you. You have the sticky slightly glowing remnants of his heat all over you, drying to your thighs, up your stomach, and a little even on your tits. From there up, there’s bruises and bite marks in varying shades of purplish-blue. He didn’t break the skin, but he got close on a few. He brings a hand up from under you to stroke where his teeth had been. 

“Are you done?” You ask, looking down. He’s still hard, but his dicks are pulsating in a different way. 

“Not yet,” He grimaces, looking down at himself. “It’s gonna be-- it’s gonna be different this time.” 

“Uh huh,” You nod, sitting up a little and feeling the strain in your muscles. How long had you guys been at it? 

“I have to do something different,” His eyes trail down your body, and stop at your entrance. He takes a shaking hand, and places it at your thigh, gently spreading your legs. You make a pleasant “mmm,” sound and so he keeps going, bringing his other hand down. You’re swollen, but still dripping from your combined juices. With his other hand, he pulls your lower lips open gently with his thumb. He freezes for a few moments, watching his cum drip out of you. You let out a weak cry as he spreads you slightly further watching more drip out. You really were his now, and he wants to scream it out to all the Devildom. 

“Levi,” 

Your voice snaps him out of his daze. He repeats, “It’s gonna be different.” His gaze turns from your core, to his own member, still twitching but faster. The two longer tentacles intertwine, pulsing against each other and becoming one unit, as thick as the can of soda you’d brought in originally. 

You swallow the saliva pooling in your mouth. “Fuck-” 

“I’m sor-” He starts to apologize. 

“Fuck, Levi, I want it.” You shake your head. It feels like there’s still electricity buzzing in your head, and it’d been the longest he’d been out of you since you started, and you felt so empty. 

He grits his teeth, and positions himself at your entrance, feeling the heat against his joined member, before pulling your legs up, so they’re resting on his shoulders. He watches himself push both of his dicks into you again, feeling drunk at the sight. 

Your voice and whole body is shaking as he seats himself fully. The buzzing has stopped and the reality of how full you are of him hits you like a train. Your walls are so swollen but so sensitive, and it made you want to scream out and thrash against him. 

He throws his head back once he’s bottomed out, smaller tentacles dancing against your clit. He can feel your heart pounding in your wet heat, feeling it pulse around him each time you let out a ragged breath. He was drowning, and felt like his lungs were going to explode. 

You both cry out as Levi starts to move, each of you chasing the heat and the fullness only the other can bring. It isn’t too long before the onslaught assaults on your hypersensitive bodies drag you both through another orgasm, with yours ripping through your body, soaking his smaller tentacles with a broken cry. 

Levi pulls your legs tight to him as he finishes, huffing out your name over and over. He brings a hand down to your belly, feeling both his organs pump you full. Your body spasms. It’s too much. You’re going to explode, and it keeps coming somehow. Your back arches off the back of the tub, and Levi brings his body down to meet yours. 

“MC, it feels so good.” His head is spinning. It’s real and you’re his, and the more he fills you up, the more it’s true. “MC, let me do it again. Let me go through my heat with you forever. You’re better than any hentai. It’s so good. It’s amazing. Want it forever.” He goes on and on, until he collapses against you. His breath is heavy and hot and sporadic, sometimes deep and other times like in quick huffs. 

It takes you both some time to come down from your high. You try to breathe steady, guiding his breaths with your own, and bring your hand up to stroke his hair. At your touch, he keens, still sensitive inside you but not wanting to pull out. He wants all his brothers, and all of the Devildom to see you’re his, and see what you let him do to you, what you asked him to do to you, the pleasure he was able to draw out of you. If you had to stay like this forever, he’d be happy to never play a video game again. 

After minutes, or maybe like a half hour? Was it an hour? ...Neither of you was sure, you ask, “Levi?” 

He’s collapsed into you at this point, still inside you but head buried between your breasts, arms at his side. “Yeah?”

“Do you know what time it is?”

“No, why?” 

“Nothing really, we probably missed class.” 

“Shit,” He says. 

“What?” 

“Lucifer’s probably mad at us.” 

“Do you wanna get up and check our phones?” 

“No,” Levi shaking his head into your chest. “I wanna stay here.” He looks up at you with his bangs barely letting his eyes show through. “I wanna stay here forever.” 

You smile at him. “Me too, but I think I hear my DDD buzzing?” 

“Hold on,” He says, bringing his tail up to grab your pants from where you had tossed them off. “It’s in here, right?” 

“Mhm,” You smile at him. He brings his tail over him and drops the pants across his back. You reach over to dig your phone out of the pocket. The buzzing has stopped so you missed the call at this point. 

You have 56 missed calls. 

And 99+ messages. 

These are problems for later you. 

And it’s-- shit what day did you come over? Well, whatever day it was, it was 8:18 in the morning. 

“We can still make breakfast, if you’re hungry.” 

Levi frowns, but then inhales. “I don’t want to, but we should eat.” While he had wanted his brothers to see and know, he didn’t want to actually live through the moment of them finding out and knowing. Maybe he could just send you in for food, and he could hide here? Oh god, your whole neck is red and blue and your hair is a mess. Part of him swelled with pride, and the other with humiliation. 

But before he can move himself to pull out, there’s a knock on the door. Just like how this all started. 

But there’s no time for either of you to answer, so Levi just shoves you further into the bathtub and pushes himself on top of you more. He puts one hand over his mouth and his other over yours, covering you both with his tail as much as he can. 

“Alright, enough’s enough!” Mammon yells. You can’t see him, but you hear him stomp his foot. Did he kick in the door? “Let MC out of here, you filthy-” 

“Shut up,” You hear Lucifer’s voice, and feel Levi blush into you. “I know you’re both in there,” He sighs. “We can all smell it. Mammon, just stay in the hallway. You didn’t need to follow me.” 

“MC’s trapped in there!!” 

“Aaaaaah,” Levi starts. He’s blushing so much, you can feel how hot  his face is. “Lucifer, I can-” 

“I don’t want to hear whatever it is.” He’s quickly cut off. You can feel his scowl. “I’m sure you forgot what today was, Leviathan?” 

He’s pushed so close into your body, you can almost feel the cogs in Levi’s brain trying to remember. His blush is contagious and you feel your own face heating up. 

You hear Lucifer put his hand in his head, and drag it down his face exasperatedly. “We have to be at Diavolo’s castle at 9am. I assumed because of….everything, you’d forgotten.” 

He had. And you had too. What day was it? What day did you come over? 

“Can you both be presentable and outside the house of lamentation in half an hour?” 

“Y-y-yes!” 

“And you too, MC?” 

You move Levi’s hand and answer. “Mhm! Sure thing!” 

“I never want to hear about any of this again. Do what you need to but just--” He grumbles. “Just do it better next time.” 

“Ok!” You both respond in tandem.  

“Good. Get ready. It’s-” He pauses to find the word. “Fragrant in here. Diavolo can probably smell you both already.” He closes the door, and you and Levi hold a stare. 

“No, hey wait!” Mammon’s voice comes from the other side of the door, and you hear the knob turning. How is there any further Levi can push you into this tub? “I ain’t done! Levi, your stupid fish ass is mine! I’m gonna post all your embarrassing pictures on Devilgram, and I'm gonna tell everyone that you get off to-” 

 “Shut up, Mammon,” You hear Lucifer huff and close the door again.
